The only form of modern/real-life settings I read are when magic/fantasy is somehow introduced. So, Modern Fantasy? Urban Fantasy? Magic-Realism? Not sure if that fits those three genre's but anyway. I once tried to write it, mine being a closer example of Magic-Realism based on a dude living in a small fictional town in a midwestern state in US, where suddenly everyone within a certain age-bracket in that town randomly developed an assortment of abilities. I tried to make it generic like DBZ type abilities. Extremely destructive and powerful teenagers basically. The problem I ran into that made me quit it before releasing it to the public was I couldn't seem to make the Real World government a potent enough threat without them resorting to blackmail/hostage situations with their family members or something else similar that only indirectly threatened them. Essentially, by having them randomly become city-destroyers overnight, I ramped the too high up on the power scale too quickly and I wanted it to be that way, but still ran into the same problems of having no local threats. I didn't want to immediately leap into the super powered teens fighting eachother until later because I planned to reveal similar instances happening elsewhere in the world but wanted a more local conflict to set it all off. Couldn't create a local conflict convincing enough for me to branch off into a wider conflict so the story fell by the wayside.
